DETAILED DESCRIPTION OF THE DRAWINGS
[0017] While the concepts of the present disclosure are susceptible
to various modifications and alternative forms, specific exemplary
embodiments thereof have been shown by way of example in the
drawings and will herein be described in detail. It should be
understood, however, that there is no intent to limit the concepts
of the present disclosure to the particular forms disclosed, but on
the contrary, the intention is to cover all modifications,
equivalents, and alternatives falling within the spirit and scope
of the present disclosure.
[0018] Referring now to FIG. 1, a PRIOR ART power tool 10 is shown.
The power tool 10 includes a power tool housing 12 that has a
"clam-shell" construction, meaning that internal components of the
power tool 10, such as the motor 18 and the motor housing 20, are
held by two halves or "clam shells" 14, 16 of the housing 12 which
are secured together (along with other housing components) to form
the housing 12. This "clam shell" housing 12 is generally divided
along a parting plane that passes through both the handle 28 of the
power tool 10 and the axis about which the rotor of the motor 18
rotates during operation (which, in this embodiment, is also the
axis about which components of an impact mechanism 30 of the power
tool 10 rotate during operation). Components of the motor housing
20 are secured together separately from the halves 14, 16 to form
the housing 20 that contains the motor 18.
[0019] The halves 14, 16 of the housing 12 are configured to
receive fasteners 22 to secure the halves 14, 16 together as shown
in PRIOR ART FIG. 1. Specifically, the half 14 is formed to include
apertures 24, and the half 16 is formed to include apertures 26.
During assembly of the tool 10, the halves 14, 16 are aligned to
permit the fasteners 22 to be received by corresponding apertures
24, 26 of the halves 14, 16. As such, the fasteners 22 extend in a
direction indicated by arrow A that is substantially perpendicular
to a direction indicated by arrow B in which the motor 18 and the
motor housing 20 extend (the arrow B being generally parallel to
the axis about which both the rotor of the motor 18 and the
components of the impact mechanism 30 rotate during operation).
[0020] In the PRIOR ART design shown in FIG. 1, the fasteners 22
are positioned both above and below the motor 18 and the motor
housing 20. In that way, the fasteners 22 extend around the motor
18 and the motor housing 20 (without passing through any component
of the motor 18 or the motor housing 20).
[0021] The halves 14, 16 are sized to allow the fasteners 22 to
extend around the motor 18 and the motor housing 20 when the tool
10 is assembled, as suggested by PRIOR ART FIG. 1. Due to the size
of the halves 14, 16, the size of the housing 12 may be undesirable
in certain situations, such as when space constraints impeding the
use of the tool 10 are present. Alternatives that enable the size
of housing 12, and thus the package size of the power tool 10, to
be reduced would therefore be beneficial in such situations.
[0022] Referring now to FIG. 2, an illustrative power tool 110
according to the present disclosure is shown. Like the power tool
10 of PRIOR ART FIG. 1, the power tool 110 shown in FIG. 2 is
illustratively embodied as a cordless, electric impact tool (in
particular, an electric, pistol-style impact tool). In various
embodiments, the power tool 110 may be embodied as a pistol-grip
impact tool, an in-line impact tool, or an angle impact tool, such
as a right-angle impact tool. The power tool 110 includes an impact
mechanism 112 that is operable to drive rotation of an output drive
114 of the power tool 110 about an axis 116, as best seen in the
cross-sectional side view of FIG. 6. It should be appreciated,
however, that in other embodiments, the power tool 110 may be
embodied as an electric power tool that does not include an impact
mechanism, such as a corded or cordless electric drill, driver, or
ratchet.
[0023] The illustrative power tool 110 includes a tool housing 118
that is broken away to show that the power tool 110 also includes a
motor housing 120 and fasteners 122, as best seen in FIG. 2. In
contrast to the PRIOR ART power tool 10 of FIG. 1, the tool housing
118 of the tool 110 is not assembled separately from the motor
housing 120 of the tool 110. Rather, the fasteners 122 are used to
secure components of both the tool housing 118 and the motor
housing 120 together, such that the motor housing 120 is supported
by the tool housing 118.
[0024] The tool housing 118 includes a hammer case 152, a body 126,
and a back cap 128, as shown in FIG. 2. The body 126 defines an
interior space 130 in which the motor housing 120 is positioned and
through which the fasteners 122 extend when the tool 110 is
assembled. The hammer case 152 is coupled to the body 126, when the
tool 110 is assembled, to close off the interior space 130 and
define an output end 134 of the tool 110. The hammer case 152 is
formed to include threaded recesses 170 that receive the threaded
ends of the fasteners 122 when the tool 110 is assembled. As such,
the hammer case 152 may be considered a "front housing" or "front
cap" of the tool housing 118. In the illustrative embodiment, the
hammer case 152 supports the impact mechanism 112 of the tool 110.
The back cap 128 is also coupled to the body 126, when the tool 110
is assembled, to close off the interior space 130 and define a back
end 132 that is positioned opposite the output end 134 of the tool
110. The back cap 128 is formed to include apertures 136 that
extend through the back cap 128 and open into the interior space
130 when the tool 110 is assembled. These apertures 136 are sized
to receive the fasteners 122 as shown in FIG. 2.
[0025] The body 126 is illustratively formed from two mirror-image
halves 126A, 126B, only one of which is shown in FIG. 2. It should
be appreciated, however, that in other embodiments, the body 126
may be formed from a single piece or from more than two pieces. The
halves 126A, 126B extend downwardly from the back cap 128 to define
a handle 124 which may be grasped by a user of the power tool 110.
The halves 126A, 126B each extend between the hammer case 152 and
the back cap 128, such that the body 126 supports the motor housing
120 when the tool 110 is assembled, as suggested by FIG. 2. In the
illustrative embodiment, the halves 126A, 126B of the body 126 are
generally divided along a parting plane that passes through both
the handle 124 and the motor housing 120.
[0026] Referring now to FIG. 3, the body 126 illustratively
includes features 127 that are used to position the halves 126A,
126B relative to one another during assembly of the tool 110.
Specifically, each of the halves 126A, 126B is formed to include a
respective flange 127A, 127B that is received by one of a pair of
corresponding channels 152A, 152B formed in the hammer case 152 of
the tool housing 118 (see FIG. 2). When the flanges 127A, 127B are
received by the channels 152A, 152B, the halves 126A, 126B are
guided toward one another around the motor housing 120 (see FIG.
2), thereby minimizing any gap between the halves 126A, 126B and
facilitating engagement of the motor housing 120 (see FIG. 2) by
the body 126 during assembly of the tool 110.
[0027] Referring now to FIGS. 4-5, the features 127 also include
projections 127C-F that are provided on each of the halves 126A and
received by the back cap 128 during assembly of the tool 110. In
the illustrative embodiment, the half 126A includes an upper
projection 127C and a lower projection 127E, while the half 126B
includes an upper projection 127D and a lower projection 127F.
During assembly of the tool 110, the halves 126A, 126B are guided
toward one another until the projections 127C, 127D align with and
engage one another and the projections 127E, 127F align with and
engage one another, thereby minimizing any gap between the halves
126A, 126B. Once the projections 127C-F of the halves 126A, 126B
align with and engage one another, the back cap 128 is engaged with
the halves 126A, 126B so that the projections 127C-F are received
by slots 129 formed in the back cap 128 (one of which is shown in
FIG. 5).
[0028] The features 127 therefore facilitate attachment of the
halves 126A, 126B of the body 126 to the hammer case 152 and the
back cap 128 to minimize any gap existing between the halves 126A,
126B during assembly of the tool 110, as shown in FIGS. 3-5. Once
the halves 126A, 126B are positioned relative to the hammer case
152 and the back cap 128 as discussed above, the fasteners 122 are
used to secure the back cap 128 to the hammer case 152, with the
halves 126A, 126B sandwiched between the back cap 128 and the
hammer case 152, to assemble the tool housing 118 of the tool
110.
[0029] Referring again to FIG. 2, the motor housing 120 includes an
end bell 138 that abuts the back cap 128 and an end bell 140 that
abuts the hammer case 152 when the tool 110 is assembled. The end
bell 140 is adjacent a transmission 160 of the power tool 110 that
extends between the end bell 140 and the impact mechanism 112, as
best seen in FIG. 6. The end bells 138, 140 cooperatively support a
rotor 156 and a stator 148 of a motor 142 of the tool 110. The end
bell 138 is formed to include grooves 144 that extend through the
end bell 138 parallel to the axis 116 Likewise, the end bell 140 is
formed to include grooves 146 that extend through the end bell 140
parallel to the axis 116. When the tool 110 is assembled as shown
in FIG. 2, the grooves 144 of the end bell 138 are aligned with the
grooves 146 of the end bell 140, both of which are aligned with the
apertures 136 of the back cap 128 and with the recesses 170 formed
in the hammer case 152.
[0030] The end bell 138 of the motor housing 120 and the back cap
128 of the tool housing 118 are illustratively separate components
as shown in, and described above with reference to, FIG. 2. It
should be appreciated, however, that in other embodiments, the end
bell 138 and the back cap 128 may be provided as a unitary or
integral component. In other words, in some embodiments, the same
component may serve as both the end bell 138 of the motor housing
120 and the back cap 128 of the tool housing 118.
[0031] The motor 142 is illustratively embodied as an electric
motor, as suggested by FIG. 2. The motor 142 includes a stationary
component, i.e., the stator 148, that is positioned between the end
bells 138, 140. The motor 142 also includes the rotor 156 which is
configured to rotate about the axis 116 to drive rotation of the
output drive 114 (via the transmission 160 and the impact mechanism
112). The stator 148 defines channels 150 that extend through the
stator 148 parallel to the axis 116. When the tool 110 is assembled
as shown in FIGS. 2 and 6, the channels 150 of the stator 148 are
aligned with the grooves 144, 146 of the end bells 138, 140, with
the apertures 136 of the back cap 128, and with the recesses 170
formed in the hammer case 152.
[0032] Referring now to FIGS. 2 and 6, the hammer case 152 of the
impact mechanism 112 supports a hammer 151 of the impact mechanism
112. As noted above, the hammer case 152 is formed to include
threaded recesses 170 that each receives a threaded end of one of
the fasteners 122. These recesses 170 each extend parallel to the
axis 116, as best seen in FIG. 6. When the tool 110 is assembled as
shown in FIGS. 2 and 6, the recesses 170 of the hammer case 152 are
aligned with the channels 150 of the stator 148, the grooves 144,
146 of the end bells 138, 140, and the apertures 136 of the back
cap 128.
[0033] The fasteners 122 are inserted through the apertures 136,
the grooves 144, the channels 150, and the grooves 146, and into
the recesses 170 when the tool 110 is assembled, as shown in FIGS.
2 and 6. The fasteners 122 secure the back cap 128 to the hammer
case 152, with the body 126 sandwiched between the back cap 128 and
hammer case 152, to form the tool housing 118. Additionally, the
fasteners 122 secure the end bells 138, 140 around the stator 148
to form the motor housing 120. In that way, the fasteners 122
secure the tool housing 118 and the motor housing 120 together so
that the motor housing 120 is supported by the tool housing
118.
[0034] The fasteners 122 illustratively extend in a direction
indicated by arrow C that is parallel to a direction indicated by
arrow D in which the motor 142 and the motor housing 120 extend, as
shown in FIGS. 2 and 6. The fasteners 122 engage the back cap 128
and extend therefrom through the interior space 130 to the hammer
case 152. The fasteners 122 illustratively include four fasteners
in the embodiment of FIGS. 2-6. It should be appreciated, however,
that in other embodiments, more or less than four fasteners may be
used. Additionally, it should be appreciated that, in some
embodiments, fasteners may not be used at all. Rather, clips or
metal tie straps, or the like, may be used.
[0035] In one respect, because the fasteners 122 extend through the
motor 142 and the motor housing 120, rather than around the motor
142 and the motor housing 120, the package size of the power tool
110 may be smaller than the package size of the power tool 110. In
another respect, because the motor housing 120 and the tool housing
118 are secured together via one set of fasteners 122, the separate
components used to secure the tool housing 12 and the motor housing
20 together may be avoided, and thus the package size of the power
tool 110 may be smaller than the package size of the power tool
10.
[0036] While certain illustrative embodiments have been described
in detail in the figures and the foregoing description, such an
illustration and description is to be considered as exemplary and
not restrictive in character, it being understood that only
illustrative embodiments have been shown and described and that all
changes and modifications that come within the spirit of the
disclosure are desired to be protected. There are a plurality of
advantages of the present disclosure arising from the various
features of the apparatus, systems, and methods described herein.
It will be noted that alternative embodiments of the apparatus,
systems, and methods of the present disclosure may not include all
of the features described yet still benefit from at least some of
the advantages of such features. Those of ordinary skill in the art
may readily devise their own implementations of the apparatus,
systems, and methods that incorporate one or more of the features
of the present disclosure.
